Stimulation Sites and Fatigue Induced by Neuromuscular Electrical Stimulation in Healthy Individuals

Neuromuscular electrical stimulation will be applied at two sites to induce fatigue with stimulation frequency specified at the Arm/Group Descriptions. The electrical stimulation parameters to generate the fatigue protocol will be: biphasic pulsed current, pulse duration of 2 ms, and on:off times of 5:10s. The fatigue protocol will be applied with a current intensity sufficient to generate an evoked torque at a level of 20% of the MVIC, which will be maintained throughout the protocol. NMES will be maintained until reaching an intervention time of 20 minutes, generating 80 evoked contractions.
